Unison offers funds for a down payment in exchange for a home ownership stake; in the case of one California homebuyer, the company matched their 10% down payment and required no monthly payments; instead the borrower must repay Unison with the sale of their house plus 35% of any real estate gains incurred from the sale; a handful of companies are offering similar real estate products including Point which offers cash-for-equity arrangements for existing homeowners.
